MINERS CHECK-PROTECTOR.

Application filed December 5, 1917.

To all whom t may concern.'

Be it known that I, GUY M. Powiem, a citizen of the United States of America, residing at Kellerman, in the county of Tus-V caloosa and State of Alabama,have invented certain new and useful Improvements in Miners Check-Protectors, of which the fol lowing is a specification. v

My invention relates to a device for preventing the removal or change of miners checks or like identifying means from mine cars or like haulage means except at the proper point and by an authorized person. Heretofore the practice has been for the miner when loading a car, to hang therein or place thereon at some suitable point a check or identifying tag which was removed at the tipple where the car was weighed and dumped and credit given to the miner as identiiied by means of his check or tag. Where the checks were hung without the car it is obvious that it was easy for them to be readily removed, lost or exchanged for the check of some other miner than the one who loaded the car and much confusion and dissatisfaction has arisen from this source. y y p Y The object of my invention is to design a simple and inexpensive protector which will be automatic in its action and will positively prevent the removal or exchange of a check until the car von which the protector is mounted has assumed a predetermined position which it is due to assume only after arriving at the tipple or point whereV the check is to be removed. More specifically, my protector comprises a member fixed to the car and a movable member, the miners the two so as to form a stop `which will prevent that relative movement of the members necessary for the removal of the check until the car has assumed a position different from that which it will normally assume while in the mine. Y Y

I have illustrated several embodiments of my invention in the accompanying drawings, in which Figure 1 shows the preferred embodiment of my invention as applied to a carin a rotary dump and moved therewith to an abnormal or tilted position.

` In its preferred embodiment, the check holder comprises a casing which is substantilted to its tially circular and composed of two seg-v ments 1 and 2, the segment 1 having a chec receiving recess 3 therein opening through its straight edge, which Vedge in normal position is vertically disposed.k The bottom 4 of this recess slopes upwardly toward this edge forming a straight inclined support for the miners check 5 which, by reason of the in-v clination, "is held against tendency to -roll out of the pocket normal position, but it will be noted that the check normally projects partly from this recess, see Fig. v2. l rIhe segment 2 is-proopening toward its straight ,edge which abuts against the straight vedge of the segment 1, this recess forming a continuation of the recess 3 and receiving the projecting part -of the check. The segment 2 at its upper end is provided with a hinge lug 7 adapted to be inserted between perforated ears 8 at the top of the segment 1 and to be pivotally connectedY thereto by a rivet or fixed pivot pin 9. The hinge lug 7 is provided with a lip 10 which extends into the upper portion of the recess 3 and has its under edgeV disposed substanwhile the protector is in tially parallel with the .inclined bottom 4r of the recess 3.V The space between the tongue 10 and the bottom 4 is Slightly greater than Y therein with 'L taining screws, bolts or "t its l:closed v position' diameter of the check 5 and the depth of the the polret is' such that the checky will vrest tially to the left (Fig. A y v angles to the bottom 4 at thepointv where the check rests thereon, which line will intersect the tongue near its free end. The recess 6 'extends substantially below the bottom 4 to receive a tongue 11 formedon the straight edge of segment 1 below thek bottom 4 and this tongue will serve to prevent any relative displacement voil"V the' segments laterally; The segment 1 has Eafla'nge v12'projecting Jr'rom its"rear'suriacev along its straight edge and this ilange is 'perforated to receive the rerivets 13, by means of which the protector is. mine I car orf like carrier. The back 'wall' of the segment 2 is correspondinglynotche'd to receive the flange l12,'it bei'ng'iioted that in the segmentv "2 protects from' interference. 5At the lower portion 'of the'segme'nt 2 Iprovide a finger gripy 14 whic projects below the curved hottonlfedge of the protector.

In operation, with the protector standing these astening's in its'` normal'position, as indicatedin Fig'.

-" the segment 2 aainst mentand moved up 2, when `itis desired tov insert a'checlr 'the miner opensE out the segment 2, thrusts his checkintothe top of the recess 6 and closes the segment 1, where-` upon "the check Irolls down 4the bottom "wall 4 to the position shown'in dotted lines Fig; 1. 'Access' cannot be had to the checlr while the protector remainsin'this, its normal po- 'of the fact that the tongue opening movement' ol the ysegment 2 'before it .clears the tongue '11er open'sfsuiiiciently for the checkto he engaged 'by anlinstruthe 'incline 4. r When,

Y however, the car reaches the dump or tipple the' check is `freev to 15m-f1 is uned thereby to an abnormal r0- V sition', such asis indicated in Fig. 2, the bottom' 4 is rocked to a reverse inclination and p roll Vdown 1t as soonas the engagement of closedposition Y p m'ent2holds it tothe position shown in under the t'ongue'lO to the position shownV in'that figure, but normally the lsegment 2 will 'tend'v to swing slightly` open, causing the Y tonguelO to bind on the-,check and'hol'di't "'in'lhe pocket until released.

These shoulders being raised above the outer face of thefplate leave between them a'vertical groove or recess extending from top to bottoin of theplatefRetaining screws 19 are passed through the intermediate and lower portion of these shoulders to 'secure the plate to thecar. Before"thel` plate is thus secured, however'," the movable element ot the 'p`r`otector Vis connectedl therewith'by having its hinge pint'les sert-ed Iin the bearingseats 1,8 in 4the plate.

which "abi'frorr'n'alB position is( preferably .the

on "which thechecl? rests position assumed an inclination away from the pocket 27 in the back plate, thus permitting the check to roll out of the 'pocket and releasing the carrier to be swung open whenl the check will fall into the hands of the operator. To facilitate the opening of the carrier, its lower edge projects below thebase vplateso asl to form a finger grip 30. It will be evident that the check protector can be arranged on the end or sides of thecar and with its check supporting surface inclined in the proper relation to the normal position of the car so4 as to prevent the check moving to unlock the carrier until the car is on the tipple or has been dumped. When the parts are assembled and locked by the check none of the fastenings that connect the two parts of the protector together or that attach the protector to the car are accessible to be tampered with.

In Figs. l2 kto 16,1 have illustrated a modification of my invention wherein the back plate 31 is provided at its corners with holes 32 and near the upper edge of its outer face with a stop lug 33. A front plate 34 having parallel side shoulders 35 extending vertically its full length is mounted over the plate 3l and secured by means of rivets or bolts 36 which pass through the shoulders 35 and the holes 32 into the body of the car. Before theparts 16 and 19 are secured together a movable check carrying element 37 is interposed between them, the body portion of this element being formed by a rectangular block or plate which rests with a snug sliding it between the vertical shoul ders 35 on the cover plate 34 and'it is provided with a check receiving pocket 38 opening through the outer side face of the member, the pocket having a back wall 39 provided with a central opening or hole 40 therein and also having top and bottom notches 41 and 42 which are diametrically opposite in a vertical plane through, and which open into, the opening 40. These notches are adapted to receive the lug 33 as the slide 37 reaches its upper or lower position and this lug therefore serves to limit its vertical movements and prevent its detachment from the back. The pocket 38 is in the form of a cylinder having its axis at an `angle of about 450 to the element 37, this arrangement producing a bottom wall which slants downwardly toward the back of the pocket and a top wall which slants upwardly away from the back of the pocket. The advantage of this will be apparent when it is observed that thecheck 28 will rest on the rearwardly sloping bottom face which will shift its bottom edge against the back edge of thel pocket and cause it to fall by gravity outwardly so that its upper edge will enter a lock pocket 43 formed in the inside face of the cover plate 34 and, when thus engaged, it will prevent the member 37 from being lifted by means of its top 44 which projects forwardly sufficiently at' its center to form a lifting lug 45 which overl hangs beyond the, plate 34. The check will retainthis position until the car reaches its abnormal dumping or tipple position which is indicated in Fig. 16, when the tilting tendencyof the sloping bottom of the pocket will be overcome and the check 'will fall against the back wall of the pocket and thusy unlatch the movable member 37 toypermitits vertical movement to check discharging position in which it will be observed that it will stand above the top edge of the car so that the finger can be passed through the hole 40 and dislodge the check. As soon as the car is righted the member 37 will'drop back to position and, when the miner has loadedhis car, the member 37 is drawn up, thc checkV inserted in the pocket 38 and the member 37 is dropped back into position in the hole, whereupon the check will fall out-- wardly and lock' the parts. Y

This invention is not intended to be restricted in scope to the specific embodiment shown, but contemplates such modifications as come within the spirit and scopeof the claims.

Having thus. described my invention, what I claim as'new and desire to secure by Let-' ters Patent, is z* j l. A miners check protector comprising a l holderv adapted to be fixed to a receptacle, a guard movable relatively to the holder, opposite shoulders on the holder and guardv between which the check is interposed to interlock them, and means to prevent the check shifting from interlocking position between said shoulders until the holder assumes a predetermined position.
